C# MathF.Cosh()用法及代码示例


Math.Cosh(Single)方法是内置的MathF类方法,它返回给定单值参数的双曲余弦值。

用法: public static float Cosh (float x);
Here, x is the number whose hyperbolic cosine is to be returned and type of this parameter is System.Single.

返回值:此方法返回System.Single类型的x的双曲余弦值。如果x等于NegativeInfinity或PositiveInfinity,则返回PositiveInfinity。如果x等于NaN,则返回NaN。


以下示例程序旨在说明上述方法的用法:

示例1:

// C# program to illustrate the 
// MathF.Cosh(Single) Method 
using System; 
  
class GFG { 
  
    // Main Method 
    public static void Main(String[] args) 
    { 
  
        float num1 = 60.0f, num2 = 0.0f, num3 = 1.0f; 
  
        // It returns the hyperbolic cosine  
        // of specified angle in radian 
        float coshvalue = MathF.Cosh(num1); 
        Console.WriteLine("The Cosh of num1 = " + coshvalue); 
  
        coshvalue = MathF.Cosh(num2); 
        Console.WriteLine("The Cosh of num2 = " + coshvalue); 
  
        coshvalue = MathF.Cosh(num3); 
        Console.WriteLine("The Cosh of num3 = " + coshvalue); 
    } 
}
输出:
The Cosh of num1 = 5.710037E+25
The Cosh of num2 = 1
The Cosh of num3 = 1.543081

示例2:

// C# praogram to illustrate the 
// MathF.Cosh(Single) Method 
using System; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
          
        float num1 = (30 * (MathF.PI)) / 180; 
          
        // calling result() method 
        result(num1); 
        result(Single.NaN); 
        result(Single.NegativeInfinity); 
        result(Single.PositiveInfinity); 
    } 
  
    // defining result() method 
    public static void result(float value) 
    { 
  
        // using the method 
        float result = MathF.Cosh(value); 
  
        // Display the value 
        Console.WriteLine("Cosh({0}) will be {1}", 
                                value, result); 
    } 
}
输出:
Cosh(0.5235988) will be 1.140238
Cosh(NaN) will be NaN
Cosh(-Infinity) will be Infinity
Cosh(Infinity) will be Infinity
